Move a site to another server

The site waralbum.ru on Wordpress.
Server in Selectel on Debian 10, there is no panel type ISPManager.

You need to move the site to another server, also in Selectel, while you need to install the ISP Manager panel (Lite license is purchased) and the site must be visible in it.

You also need to migrate the main server settings, including FastCGI (Nginx PHP-FPM), CROWN.
PHP costs 7.1.33, you need to put a newer one (Wordpress recommends a minimum of 7.4).

Settings should be done as much as possible through the ISP Manager, so that later I can see them through the panel and can change them if necessary.

New server on Debian 11 x86_64. It has 4 disks of 1 TB. In the provider panel it is indicated
RAID1 LVM, you need to configure if necessary to have Raid 1 - disk mirroring.

I am considering suggestions from experts with feedback in this area.
